BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name ‘Hilmoocour’.

The new Echinacea plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to develop new strong and freely flowering Echinacea plants with attractive inflorescences and good garden performance.

The new Echinacea plant originated from an open-pollination in March, 2008 in De Kwakel, The Netherlands of a proprietary selection of Echinacea purpurea identified as code designation T 1236, not patented, as the female, or seed, parent with an unknown selection of Echinacea purpurea as the male, or pollen, parent. The new Echinacea plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination grown in a controlled greenhouse environment in De Kwakel, The Netherlands in May, 2010.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in De Kwakel, The Netherlands since January, 2016 has shown that the unique features of this new Echinacea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Echinacea have been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hilmoocour’. These characteristics in combination distinguish ‘Hilmoocour’ as a new and distinct Echinacea plant:

-   -   1. Upright to somewhat outward plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit, dense and bushy appearance.     -   4. Strong and healthy roots and leaves.     -   5. Dark green-colored leaves.     -   6. Freely flowering habit.     -   7. Strong flowering stems.     -   8. Large inflorescences with red purple-colored ray florets.     -   9. Good garden performance.

Plants of the new Echinacea can be compared to plants of the female parent selection. Plants of the new Echinacea differ from plants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Echinacea are darker green in         color than leaves of plants of the female parent selection.     -   2. Plants of the new Echinacea are more freely flowering than         plants of the female parent selection.     -   3. Plants of the new Echinacea have larger inflorescences than         plants of the female parent selection.     -   4. Ray florets of plants of the new Echinacea are darker red         purple in color than ray florets of plants of the female parent         selection.

Plants of the new Echinacea can be compared to plants of Echinacea purpurea ‘Hilmoooawak’, disclosed in a U.S. Plant patent application Ser. No. 14/756,665, now abandoned. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘Hilmoooawak’ in the following characteristics:

-   -   1. Plants of the new Echinacea are more compact and have shorter         peduncles than plants of ‘Hilmoooawak’.     -   2. Plants of the new Echinacea are more freely flowering than         plants of ‘Hilmoooawak’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Echinacea plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Echinacea plant.

The photograph (FIG. 1) is a side perspective view of a typical flowering plant of ‘Hilmoocour’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring and summer in 15-cm containers in a glass-covered greenhouse and “finished” in an outdoor nursery in De Kwakel, The Netherlands under cultural practices typically used in commercial Echinacea production. During the production of the plants, greenhouse day temperatures ranged from 12° C. to 14° C., outdoor nursery day temperatures ranged from 14° C. to 20°, greenhouse night temperatures ranged from 12° to 14° and outdoor nursery night temperatures ranged from 7° C. to 15° C. Plants were 25 weeks from planting when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
